Abstract: A resettable mechanical disconnect comprises: first and second shafts having coupling features to engage each other such that first and second shafts rotate together around first axis; axial surface of ramp increasing in height around outer surface of second shaft around first axis; pawl and spring to rotate toward radial surface of ramp of second shaft; movable pin to retain pawl in place away from ramp when extended; control mechanism to retract movable pin; when control mechanism causes movable pin to retract, spring causes pawl to rotate about second axis to contact radial surface of ramp; pawl applies pressure against ramp as it rotates and pressure of pawl against increase in height of axial surface of ramp causes second shaft to move away from first shaft axially along first axis such that coupling features shafts disengage to cause first shaft and second shaft to no longer rotate together.

Abstract: A bleed system including control circuitry and one or more jet pump assemblies. The control circuitry is configured to receive a signal indicative of a fluid parameter in the bleed system and cause the one or more jet pump assemblies to alter a mixing ratio of a higher pressure gas and a lower pressure gas based on the signal. The one or more jet pump assemblies are configured to combine the lower pressure gas and the higher pressure gas to generate a supply gas. The one or more jet pump assemblies are configured to provide the supply gas to one or more gas loads in the bleed system. In examples, the control circuitry is configured to establish a system setpoint for the fluid parameter based on an operating status of the one or more gas loads.

Abstract: A system and method for measuring an amount of backlash in an actuator assembly that includes a housing assembly, an actuator, a drive source, an actuator position sensor, a drive source position sensor, and a controller. The controller is in operable communication with the drive source, the actuator position sensor, and the drive source position sensor, and is configured to selectively implement a built-in test that determines the amount of backlash in the actuator assembly.
